In a page that I am working on right now I have this problem:
I have a dropdown menu using select. This menu has two options. What I want to happen is that when I click the first option another dropdown menu (let us call it B), is disabled. And when I click the second option, menu B is enabled. I've tried to solve it this way:
<option onClick='dm();' onSelect='dm();' value='DM'>Option 1</option>
<option onClick='rm();' onSelect='rm();' value='RM'>Option 2 </option>
</select>
(As you can see, I've defined both onClick and onSelect trying to make it work).
The javascript code is in a file called util.js. This is the code:
alert("OK");
document.newMalForm.menuB.disabled="disabled";
return;
}
function rm(){
alert("OK");
document.newMalForm.menuB.disabled=false;
return;
}
The javascript file is included using this tag:
Now, this works in firefox but not in IE.
In fact, IE doesn't even run the functions as the alert (called in the
javascript file) isn't shown when I click the menu options. What is the
problem?
EDIT: The alert only exists in debug purpose. And I also wanted to say that this is my first post in this forum!
More editing, to clarify: newMalForm is the form that contains both of the dropdown menus.

Remove the events from the options, use an event directly on the select instead.
Internet Explorer treats select
boxes slightly different than the rest of the document, (if you've ever
read anyhting about "windowed controlls" you know what I'm talking
about)
I'm thinking IE doesn't notice events in childnodes of select elements, only the select elements themselves.
I normally setup my functions to work depending on either of the selects value or selectedIndex attribute & using the onchange event.
function dis(state){
var disState = state == 1;
alert(disState);
}
...
<select onchange="dis(this.selectedIndex)">
<option>Disabled</option>
<option>Enabled</option>
</select>
